Frequently asked questions

Can a standard strap be fitted to the Royal Oak 26591IP.OO.1252IP.01?

No. The bracelet is integrated directly into the case: there is no standard lug to attach a conventional strap. This is a closed architecture, designed that way since 1972. The only option is to build a bespoke attachment, shaped around the watch itself.

How does the bespoke strap service work for this Royal Oak?

I work through <a href="/pages/casati-booking">Casati Milano</a>, by appointment only, at Via XX Settembre 15 in Milan. I bring the watch to the bench, take measurements directly from the case, and build the attachment around its original proportions. There are no templates: every piece is made from scratch for that specific case.

Which leather do I recommend for this Royal Oak in titanium and platinum?

I recommend naturally aged Barenia. The character of this watch is sporting yet refined, with a combination of materials that does not shout: titanium is discreet, platinum is cold and dense. Barenia follows the same register — it starts almost stiff, then softens and takes on the colour of time. It is a leather that grows with the watch, not against it.

How long does a well-made strap last?

With quality leather and serious construction, I expect five years of daily wear, often more. It depends on how you wear it and how much care you give it. An occasional treatment with a nourishing cream, keeping the leather away from prolonged water exposure: small things, but they matter. Ageing on leathers like Barenia is not deterioration — it is accumulated character.

What makes building a strap for the Royal Oak technically complex?

The geometry of the eight hexagonal bezel elements extends into the bracelet with precise visual continuity. Breaking that continuity with a rough attachment is immediately obvious. I work with millimetric patience to maintain the proportions Genta drew: the strap must look like part of the watch, not an addition.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
